i remember so many details about this webtoon/manhua whatever the hell but not the name.
its like a highschool in hell setting, i remember one of the first scenes was about the main character recieving his uniform later than other kids in high school, he wanted to impress other kids with his name being Satan but a bunch of other kids were also named Satan, theres this like tournament/contest thingy?? where it was supposed to be like a sneaking around challenge, and the competitor literally wore flashy clothes because of how good they were at fitting into the background but one of their characters literally won by being super hot and there’s also three gods iirc, one omnipotent, one omniscient, and the like ACTUAL god.
this guy reincarnates to different lives where he has to join the hero’s party and then be kicked out before he goes onto another world where he does it again and he repeats this 100 times before he ends up in this space with 100 doors leading to every one of his past lives. i forgot why specifically but he goes back to his very first life where he meets this dying elf mage girl that he used to be in the hero’s party with so he decides to go back in time to when he first met them.
